I recently tested my max hold for the pre reqs just so I could go back latter and compare. I have a onld shoulder injury and on the arch hold I think I could hold my legs and upper body in position for a while, but with my injured shoulder I can only hold that arm up and out infront for about a minute.
For comparison I can dead hang for 1m45s (might be wrong grip, I did it pull up style)
p-bar support 2m
hollow hold 1m (it took me a week or so to get this)
plank 2m30s I think it was my back and legs that got wobbly here.
r. plank 3m30s At 3.5 it was my stomach that was about to give out. I let down to keep from falling down later.
I guess what I am wondering is what aspect of the arch hold is most important? Is it the core stuff? or holding your arms out?
Thanks.
